CASE STUDY | CLATTERBRIDGE CANCER CENTRE based on the clinical function of each space. A lot of areas are not defined in the HTM [Health Technical Memoranda], so, during the early stages, we sat down with the users to understand their requirements for each space. We then proposed environmental conditions to ensure infection-control procedures and air change rates that would allow staff to carry out procedures successfully, explains Taylor. Glazed cladding The building envelope features a glazed, curtain wall cladding system. One of the key challenges was that the building needed to be visually striking, so the design went down the route of a glazed cladding system, Taylor says. In helping to develop the design, Aecom undertook an assessment to ensure the envelope achieved an appropriate annual balance between the rate of heat loss and the amount of solar gain, to minimise energy consumption during both heating and cooling seasons. The assessment of solar gain included energy saved by a reduction in the need for artificial lighting. Cancer patients can be very sensitive to environmental conditions, so while the glazed faade provides patients with views out over the city of Liverpool Aecom had to ensure it had no detrimental effects on the thermal comfort of patients. It used IES software to model Circulation areas, entrances and basement waiting areas are all naturally ventilated CARE LIFETIME SUPPORT Rely on us for Lifetime Support, from design and specification through to manufacture and aftercare.
